"The erosion / corrosion resistant coating developed by MPT is amulti-layered, thin "titanium-nitride" coating that effectivelyresists erosion throughout the erosive particle impingementregime from low to high angles of impact. The coating is appliedby using a Cathodic Arc Physical Vapor Deposition coatingmachine. The coating application may be modified to optimize thecoating for various applications. For example, a more corrosionresistant and less erosion resistant coating can be applied usingthe same CATARC PVD process to address the operationalrequirements of the user. The coating can be applied on variousmaterial types such as titanium, nickel and steel alloys andvarious engine types from small helicopter engines to largerturbofan engines. The coating can be used for aircraft, ship andindustrial applications.BENEFITS: The U.S. Military Services experience significant rates of erosion and corrosion on gas turbine engine compressor systems that effects engine performance, aircraft readiness and total cost of ownership. The erosion / corrosion resistant coatingcan be optimized and applied on most gas turbine engines powering air vehicles, tanks and ships. The potential market extends beyond military applications to commercial uses such as helicopters, commercial airlines and industrial power plants.Significant cost savings can be realized annually by not scrapping compressor airfoils due to erosion and corrosion.
